SEPARABLE HINGE.

- Specification ofLetters Patent.

Application filed February 23, 1909. Serial No. 479,371.

on y to take the closed position of t e partsv connected by the hinge, but also to take an open position of said parts and to lock said parts in said open position.

In the drawings :Figure 1 is. a perspec-.

tive view from one side of one of the parts of the hinge; Fig. 2 is a perspective view of the same part taken from the other side; Fig. 3

is a perspective View of the otherpart of the hinge; F 1g. 4 isa vertical section through the two parts of the hinge when the parts which they connect are in-the closed position Fig. 5 y

is a vertical section through the same parts when they are open and locked open; and

part towhich it belongs.

Fig; 6 is a pore ectiveview of the two parts of the hinge, s owing them in, the lockedopen position. The hinge consists of two plates, each attached to one of two parts. One of the hinge plates may be called the socket plate, and consists ofa sheet of metal 1 having a suitable aperture 2 therein. Screw holes are provided for fastening the socket plateto the From the inner edge of one side of the aperture, an integral flange extends downward from the plate 1. This flange may be used if desired, but is not an essential portion of the hinge. It'serves to guide the entrance of the other art through the socket, and to act as an-a utment in placing the plate 'injposition on the part to which it pertains. aperture 2, andbeneath the plate 1, is a laterally open socket 4 parallel to'and immedi- "ately beneath ,the'lowerfaceof said plate 1.

This may be made in various ways .so as to produce a socket in the position and of the character suitable 'to .produce the function her'ein mentioned; In the specific device shown in the drawings, the socket is formed from an integral tongue 5 'ex tendingfrom one edge of the plate land which is bent downereinafter dedjacent to theward and then underneath and parallel to the lower face ofthe late 1, thus producing the socket mentionec adjacent to the aperture .2. Y

. The tongue plate 6 which cooperates With the'so'cket plate is shown in Fig; 3, and has screw holes in it. Extendingfromthe plate 6, and substantially at right angles thereto, is the tongue 7, having a portion'8 arranged in one plane and a portion 9 arranged in an- .other ofi'set plane, so that, as shown in Fi s.

4, 5, and 6, the portion 8 may rest upon t e top of the plate 1, while the er'tion 9 rests against the lower surface of t e same plate when the hinge is in the open osition. The portion!) is of such length an form as to be capable of extendinginto the socket 4 when the plate 6 is at right angles to the plate 1, and when the parts are in this position (as shown in Figs. 5 and 6), the cover 12 of a box, for instance, attached to the plate 6 will be looked open with reference tothe side 13 of the box to which the plate 1 is attached and the cover cannot, by some slight shock, fall or close.

The tongue 5 and socket 4 are. laterally displaced with reference to the aperture 2 in necessary. The aperture 2 is of such length the plate 1, and in order to insert the tongue asto permit this movement, and yet to fit closely upon the edges of the portion 8 of the tongue 7 when the parts take the closed position' shown in'Fi 4. In 'order to cause the parts" to fit wel and to move together easily to the various positions,- the part 8 at the full width of the lengt of the aperture 2. Below that, the ortion 8jis tapered inany suitable Way. hen adjacent to the same broad bearing of the part 8 of the tongue '7 upon the top ofithe plate ,Land a :hroad hearing of the extremity .9 ofthe tongue '7 against the lowerside of-the plate 1 Within the socket .4; order to releasethe interlocked hinge parts from the locked-open position, thetongue must be moved m a direction opposite tothat of the locking move;

What I claim is i. In a separable hinge, a socket plate having an aperture, a tongue plate having a, tongueedapted to extend through said aperture, the said two plates being constructed to interlock on m'overnent of the tongue in the aperture in a direction parallel with the axis of rotation when the hinge is in the open iosition, whereby the same must be 1111- locked by opposite lateral movement before the hinge can take the closed position.

ill in a separabha. hinge, a socket plate having an aperture and a socket, a tongue 1 plate having a tongue extending through said aperture, and having a, part constructed to enter the socket by an additional movement in a direction parallel with the axis of rotation when the hinge is in the open position, WllOlKilrYtlH} tongue plate must be unlocked by an opposite movement before the hinge can take the closed position.

3. in a separable hinge, a socket plate having an aperture and a laterally-open socket, a tongue plate having a tongue extending through said aperture and having; a part cmistruc-tml to project beyond said aperture and. enter said socket by movement in the aperture in a direction parallel with the axis of rotation when the hinge is in the open position, whereby the tongue plate must be unlocked by opposite lateral movi went beloro the hinge can take the closed position.

ml. llnga separable hinge, a socket plate having an aperture and a laterally-open socket beneath said plale and adjacent to tinaperlnrv, a t ngue plulrhaving a tongue extending through said aperture and baring its end constructed to enter said socket by movement in the aperture in av direction parallel 'with the axis of rotation when the lnne'e is in the open position, whereby the tongue plate must be unlocked by opposite lateral movement before the hinge can take the closed position.

5. In a separable hinge, a socket plate having an aperture and a laterally-open socket, a, tongue plate having a tongue o.\'-- tending through said aperture and having a notch on one edge and apart constructed to enter said socket by lateral movement ol the tongue in the aperture when the hinge is in theopen position, whereby the notch spans the edge of the aperture when the hinge is locked andthe tongue plate must be unlocked by opposite lateral movement before the hinge can take the closed position.

(5. In a separable hinge, a. socket plate having an aperture and a laterally-open socket beneath said plate and adjacent lo the aperture, a tongue plate extending through said aperture and tapered having a, tongue adjacent to its base and substantially fitting the aperture at its base and having its end reduced in width and constrncted to enter said socket by lUUVml'Hllll,

in the aperture in a direction nrrallolwith the axis of rotation when the hinge is in the open position, whereby the tongue plate must be unlocked by opposite lateral inovoineut bel'ore the hinge can take the closed position.
